@Spartan is correct on the security though. Whether you log in or not, the database of users and passwords are now accessible to anyone with a browser instead of needing a client to access it.
You don't know this for sure. If it did happen, I promise BS would do anything they can to cover it up. Also, if someone hacked the site, UO accounts would probably be a secondary interest at best. There are other things that those usernames and passwords could be used for that are far more lucrative. There are places on the internet that pay for username and password data obtained by hacking websites just like the one in question. Nobody cares about all the pixels you've collected when they can get cash instead.
This cannot be stressed enough:
Using a different username and/or password for all of your online accounts should be a very common practice, yet the minor inconvenience causes most people to not follow this basic rule. This is why it is unacceptable for BS to use game credentials to log in to their forum, as it takes away the freedom of their customers to follow very basic web security practices.
Wait! Am I in a thread about an add-on deed book? Since I'm here... Sure, make a book... Make it unblessed and unbless all add-on deeds too while you're at it. Too much blessed junk exists as it is. I couldn't even steal a guys coffin at a funeral a few weeks ago... Pancakes!
